of the highway has been rebuilt as today's East Fork Road, but north of Heaton Flat little remains except for the Bridge to Nowhere, a tall arch bridge that was saved due to its height above the floodwaters. Located about from the nearest road, the bridge is now a popular destination for hikers and bungee jumpers. Riverside and Orange Counties In Riverside and Orange Counties, the Santa Ana River reached a peak flow of about , completely overwhelming the surrounding dikes and transforming low-lying parts of Riverside County and Orange County into huge, shallow lakes. A reporter for the Los Angeles Times described the river as "swollen crazy-mad". Forty-three people were killed in Atwood and La Jolla in Placentia. Flooding in the city of Riverside took another 15 lives. The cities of Anaheim and Santa Ana in Orange County, were flooded up to deep for several weeks. High Desert Although most of the damage occurred on the windward (southwestern) side of the San Gabriel and San Bernardino Mountains, large amounts of rain also fell on the northeast side which drains to the Mojave Desert. The Little Rock Dam on Little Rock Creek overtopped during the flood due to a damaged spillway siphon that had been plugged by debris; hundreds of people in downstream Palmdale were evacuated. Further east, the Mojave River burst its banks, damaging long stretches of the ATSF railroad and causing damage in Victorville and Barstow. The main line between Barstow and Los Angeles was closed for a week. The Southern Pacific Railroad main line over Tehachapi Pass was closed for two weeks, requiring emergency service via buses and trucks. Aftermath Dams such as those at San Gabriel and Big Tujunga greatly reduced downstream damage in the 1938 flood. Many even larger dams were built after the flood to provide a greater degree of protection to downstream communities. Hansen Dam had already begun construction but stood incomplete during the 1938 flood and was unable to prevent the devastating flooding along Tujunga Wash. The dam was completed two years later, in 1940. The Sepulveda Dam was built in 1941 to prevent the Los Angeles River from flooding the lower San Fernando Valley, Burbank and Glendale. Along the San Gabriel River, the Santa Fe Dam and Whittier Narrows Dam had both been proposed prior to 1938, but had little political support until the devastation of the 1938 flood, after which
